Abstract
A cable includes a cable core including one or more electric wires, a shield layer covering around the cable core, and a sheath covering around the shield layer. The shield layer is composed of a braided shield including a plurality of first metal wires composed of aluminum or aluminum alloy and a plurality of second metal wires composed of copper or copper alloy. The plurality of first metal wires and the plurality of second metal wires are cross-braided.
Claims16
A cable, comprising:
- a cable core comprising one or more electric wires, each comprising a conductor and an insulator covering around the conductor;
- a sheath covering around the cable core;
- and
- a double-layer structure intervening layer provided between the cable core and the sheath, and comprising a first intervening layer and a second intervening layer,
- wherein the first intervening layer covers the cable core and is in contact with the cable core, and comprises a binder tape layer composed of a paper tape, a non-woven fabric tape, or a resin tape,
- wherein the second intervening layer covers the first intervening layer and is in contact with the first intervening layer, and comprises a shield layer,
- wherein the shield layer comprises a braided shield including first metal wires comprising aluminum or aluminum alloy, and second metal wires comprising copper or copper alloy,
- wherein the first metal wires and the second metal wires are cross-braided,
- wherein a cross-sectional area of each of the first metal wires is 1.5 times or more and 2.0 times or less a cross-sectional area of each of the second metal wires, and
- wherein a ratio of a total cross-sectional area of the first metal wires to a total cross-sectional area of the second metal wires in the cross-sectional view perpendicular to the cable longitudinal direction is 1.22 or more and 1.86 or less.
